Not so rare that you can ignore them, though. When I was a kid, my Dad
had a 100ft. CB antenna mounted on the house; the grounding wire snaked
past my bedroom window. We had a direct strike, and it blew out the old
B&W TV I had plugged into the outlet near the grounding wire. The CRT
glowed for about ten minutes. It was impressive :) I've lost several
modems (three dialup and one cable) from lightning over the past ten
years, all from direct or near-direct strikes - and I haven't had a BAT
since I was 11 and the guys snapped in high wind and took it down. NC
seems to have a lot more lightning than I remember from Maine...
